the petrol gets into the bottom part of the carb where the is a little round cup like reservoir but I reckon petrol should go up the tubes into the part where the air rushes in and the spark is on the other end. I cleaned everything including fuel tank and tubes and carburator. but after the air pressure clean will see if fix the issue.

Sounds like jets (in the carbie) are blocked and/or the throttle isn't set correctly. You'll know if after trying to start it (and wearing yourself out ) and then check the plug. If the spark plug is wet with fuel then theere probably isn't enough air (choke on or similar). If plug is still bone dry then maybe carb idle screw is set wrong (or jets blocked) and its not getting enough fuel to start.

Thank you so much to you all for your ideas and replies Im happy to report that was the jets blocked as now all works great. I managed to boot the system after clearing out the viruses blocking the pipelines and I even managed to reboot to confirm it all works fine and yep all does work great..

GamerOC: I discovered yesterday that my lawnmower would not start no matter how hard i pull the flipping cord then I used my pc troubleshooting skills to see if I could fix it like I fixed my LCD tv a few months back...doh

1- I check for overheating like in the PC so I pop the sparkplug out and seemed ok. 2- I tested then the PSU like the paper clip trick I pull the cord and banged the spark plug against the motor body and a pathetic spark came out so I replaced sparkplug. 3- I did a clean up like my regular PC clean up with compressed air at my local petrol station and after cleaning the ouside of the motor(heatsink), air filter ( fans and grills). and still no picture. 4- Must be thermaltake water cooling getting stale so I cleaned the fuel pipes and the fuel tank and put some new petrol and omg still does not start....Im about to kick this @#$ down a clift by now. 5- to be continue Im going now to clear the carburator and see what happens.

If anyone here have any tricks and would like to help me out by sharing I will be grateful,

Andy. If you don't already do this, it's a good idea when you turn the beast off (especially for longer periods of non use, like over winter) to drain the carbie. Easiest way to do it is to shut the mower down by turning off the fuel. Engine will run for a minute or soo whilst it uses whats in the carb.

Fuel sitting stagnant in the carb (for long periods) tends to go stale, which is whats happened here. And in the worst case you get a coating (of shellac) through everything. In Jets this effectively blocks them.
